How do you know there is a hole in the piston? Visual check with a scope?


If the compression test shows 0psi in that cylinder, that could be a few things other than a hole in the piston.


If there truly is a hole in the piston, the whole engine needs to come out, so removing a pan is a waste of time. You also need to figure out why it's running lean enough to burn a hole in a piston. But if it's just a stuck valve, fixing that is much simpler, and the engine does not have to come out, and removing the pan would still be a waste of time.


But, to remove the pan with the engine in the truck, all you have to do is remove the motor mount bolts, loosen the transmission bolts at the crossmember, and jack the engine up until it contacts the firewall. You may want to also remove the radiator fan shroud. Once the engine is up all the way, remove the motor mounts and replace with tall blocks of wood, then drop the engine on the blocks. That gives you enough room to get the pan down enough to see inside. If you remove the radiator, I believe you can slide the pan out from the front. You have to remove the pickup tube and let it drop into the pan, then remember to reinstall it before bolting the pan back up.

 

Well after some decisions the ride to work needs to be fixed and it's on a stand upside down wit the pan off
